    definition of ITypeInfo

    Hello everyone,


    Could anyone post or let me know where is the definition of ITypeInfo please?

    (my purpose is to find its inheritance relationship, i.e. whether inherits from IUnknown or something)

    I searched all VC sub-directory and only get (in afxstat_.h),

    Code:
    struct ITypeInfo;
    typedef ITypeInfo* LPTYPEINFO;

    thanks in advance,
    George

    COM questions belong in the Windows forum.

    IDispatch is defined in OAIdl.h from the platform SDK.

    All COM interfaces derived directly or indirectly from IUnknown.
    All the buzzt!

    Thanks CornedBee,


    I have found it. In "OAIdl.h", OA is short for?
